Mitsubishi – Mr. Slim JX Series 115V Wall Mount Heat Pump | R-454B | Toronto & GTA Installation Included
Mitsubishi – Mr. Slim JX Series 115V Wall Mount Heat Pump | R-454B | Toronto & GTA Installation Included
The Mitsubishi Mr. Slim JX Series is the only wall mount heat pump in the Mr. Slim lineup that runs on a standard 115V household outlet — no dedicated 240V circuit, no electrical panel upgrade required in most homes. Powered by next-generation R-454B low-GWP refrigerant and an inverter-driven compressor, the JX Series delivers efficient year-round heating and cooling with heating operation down to -25°C (-14°F). Available in 9,000 and 12,000 BTU. All prices include standard professional installation with up to 20 ft of lineset.
The 115V Advantage — Why This Matters
Every other ductless heat pump on the market — including the Mitsubishi GX and FX Series — requires a dedicated 208-230V circuit and in many cases an electrical panel upgrade. The JX Series is different:
- Plugs into a standard 15A or 20A household circuit — the same circuit type used for appliances and outlets throughout your home
- No panel upgrade required in most homes — saving $800–$2,500+ in electrical costs
- Ideal for condos, apartments, older homes, garages, and additions where running a new 240V circuit is difficult or cost-prohibitive
- Faster, simpler installation — no electrician coordination required in many cases
- Lower total project cost — same great Mitsubishi quality and efficiency without the electrical overhead
Note: A dedicated 15A circuit (9K) or 20A circuit (12K) is still required for the outdoor unit. If your home does not have an available circuit near the installation location, electrical work will be quoted separately. Contact Bison Air to confirm your electrical situation before purchase.
